Abstract
The purpose of the study is to evaluate samples of the Cannabis sativa plant for the possibility of using them as a source of essential oils. Objectives: to establish methods for hydrodistillation of essential oil from samples of Cannabis sativa variety Maria, obtained by different fermentation methods, to determine the most effective method for obtaining essential oil that meets the requirements for the mass fraction of essential oil and physicochemical parameters; to determine the qualitative and quantitative characteristics of the essential oil of the studied objects of research. The objects of the study are fresh leaves and inflorescences of Cannabis sativa variety Maria, collected in September 2023 from a plantation in the Sukhobuzimsky district of the Krasnoyarsk Region, and fermented leaves and inflorescences of Cannabis sativa variety Maria, collected from a plantation in the Ermakovo District of the Krasnoyarsk Region in 2021. Two methods were used for fermentation: natural and with specified parameters. The hydrodistillation process was studied on a standard Clevenger-type apparatus for 5 hours, the obtained samples of essential oils were studied by volume of output in accordance with the method of isola¬ting essential oils, quality indicators and the mass fraction of essential oils were determined. The volume of essential oil obtained in experimental samples directly depends on the time of the distillation process and the conditions of Cannabis sativa fermentation. The largest amount of hemp essential oil was obtained from fresh leaves and inflorescences of Cannabis sativa variety Maria (0.42 %) from the average value of the samples. The organoleptic and physicochemical characteristics of the essential oil obtained as a result of fermentation meet the requirements for essential oils. The use of different methods of fermentation of leaves and inflorescences of Cannabis sativa affects not only the yield of essential oil, but also to a large extent its quality.
